Feb 17, 2024

The c.1084A>G (p.I362V) alteration is located in exon 5 (coding exon 4) of the ZNF350 gene. This alteration results from a A to G substitution at nucleotide position 1084, causing the isoleucine (I) at amino acid position 362 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
